• Brazil Securities and Exchange Commission has authorised B3 to launch the country’s first regulated prediction market product under securities oversight.
• Trading will initially be limited to professional investors with more than R$10 million in assets.
• B3 plans to start with binary contracts framed as yes or no outcomes linked to the US dollar, the Ibovespa, and bitcoin.
• The move positions prediction style event trading inside capital markets regulation rather than Brazil’s sports betting framework, overseen by the Ministry of Finance.
• The development lands as the United States faces escalating state-level challenges to prediction market operators, including fresh action in Nevada against Kalshi.

Brazil’s financial regulators have opened the door to a domestically regulated prediction market, taking an approach that treats event-style contracts as securities activity rather than as a gambling product.

The country’s Securities and Exchange Commission, known as CVM, has approved B3 to operate what is being framed as Brazil’s first prediction market. B3 is expected to launch the product in the first quarter of 2026, with early trading restricted to professional investors who hold more than R$10 million in assets.

At launch, B3 plans to focus on binary contracts that resolve to a yes or no outcome. The initial list of references cited for those contracts includes the US dollar, the Ibovespa, and bitcoin, placing the product squarely within a financial markets context rather than consumer betting.

The regulatory classification matters because Brazil’s online betting market launched last year under the Ministry of Finance via the Secretariat of Prizes and Bets. By keeping B3’s event contracts under CVM oversight, Brazil is drawing a boundary between securities-style derivatives activity and the newly regulated betting sector, even as both can involve risk-taking on uncertain outcomes.

The approval also arrives amid a wider debate, in Brazil and elsewhere, over which public body should set the rules for prediction markets. In the United States, prediction market oversight has become a flashpoint between state gambling regulators and the federal Commodity Futures Trading Commission. That tension has sharpened in recent days, with Nevada filing suit to block Kalshi from offering sports-linked event contracts in the state, following a federal appeals court decision that cleared the way for enforcement action.

Separately, Kalshi has signalled interest in Brazil as a possible expansion market in 2026, underlining how regulatory pathways in major jurisdictions are now shaping where prediction market operators choose to invest and launch.

Brazil’s decision to house the first approved product inside securities regulation is a deliberate choice that reduces the immediate cultural and political baggage that follows gambling debates. By limiting access to professional investors and anchoring the first contracts to established financial references, CVM is effectively framing the activity as a familiar derivatives adjacent instrument, not a mass market betting proposition.

That does not mean the risk disappears; it simply changes shape. If retail pressure builds, or if the contract menu moves beyond financial references into politics, sport, or entertainment, the question of which rulebook applies will intensify. Brazil is already running a parallel framework for online betting under the Ministry of Finance, so any perceived overlap will invite arguments about consumer protection, market integrity, and who has enforcement authority.

The contrast with the United States is instructive for operators watching global expansion. US litigation is being driven by the claim that sports-linked event contracts function like wagering, triggering state licensing requirements, while operators argue federal preemption through commodities oversight. Brazil is trying to avoid that collision by setting a narrower initial lane. Whether it holds will depend on product design discipline and on how quickly the market pushes beyond professional investors into broader participation.
